P-onset A, the onset of P-wave on the ECG to the onset of A-wave on the transmitral flow; P-onset A', the onset of P-wave on the ECG to the onset of A'-wave on the LV septal wall of tissue Doppler imaging; P-p A', the onset of P-wave on the ECG to the peak A'-wave on the LV septal wall of tissue Doppler imaging; P-pA, the onset of P-wave on the ECG to the peak A-wave on the transmitral flow; R-E', peak R-wave on the ECG to the peak E'-wave on the LV septal wall of tissue Doppler imaging; R-onset E, peak R-wave on the ECG to the onset of E-wave on the transmitral flow; R-onset E': peak R-wave on the ECG to the onset of E'-wave on the LV septal wall of tissue Doppler imaging; R-pE, peak R-wave on the ECG to the peak E-wave on the transmitral flow.
